Objectives: Forkhead box A2 (Foxa2) is a transcription factor that plays a key role in foregut, pancreatic and central nervous system development. Here, we describe a 7 years old boy whose phenotype is consistent with FOXA2 defect.Case: A 3 months old boy was referred for recurrent hypoglycemic events. He was born to unrelated parents at term with a birth weight of 3690 gr. At 6 hours of life he had severe hypoglycemia (...

Background: Paternally expressed mono-allelic pathogenic variants in the MAGEL2 (melanoma antigen L2) gene cause Schaaf-Yang syndrome (SHFYNG), a multisystem disorder with psychomotor delay, intellectual disability, behavioral abnormalities, and obesity. Severity of the disease is highly variable, some patients may die in utero and some can live with moderate disabilities. MAGEL2 gene is located in the 15q11.2– q13 region which includes...

Background: DEAH-box protein DHX37, encodes an RNA helicase, is involved in ribosome biogenesis. Monoallelic mutations in DHX37 gene have recently been identified in 46,XY differences/disorders of sex development (DSD) patients with nonsyndromic gonadal dysgenesis as well as testicular regression, while biallelic mutations have been associated with microcephaly and structural brain abnormalities. Here, we present a patient with penoscrotal hypospadias and bil...

Background: Congenital hypopituitarism (CH) refers to a deficiency of one or more pituitary hormones resulting from variants in genes encoding transcription factors for pituitary development. CH cases are mostly sporadic but 5-30% can be familial. Genetic etiology is not determined in most cases. The aim of our study was to evaluate the genetic features of CH using different molecular and/or molecular cytogenetic techniques.Subje...

Objective: Several studies have shown that sleep plays an important role as a modulator of metabolic homeostasis. Indeed, hundreds of studies have been published to examine the relationship between insufficient sleep, late bedtime and obesity. We have studied bedtime snack as another parameter. We suggested that it may be a risk factor for obesity. When we looked at the literature, we could not find any study about bedtime snack in childhood, but there are a few studies in adu...

Background: Bone morphogenetic protein 15 (BMP15), is an oocyte-specific growth factor, that regulates folliculogenesis and ovulation rate. It is encoded by the BMP15 gene (chromosome Xp11.2), in which heterozygous missense variants in the precursor or mature peptide cause primary ovarian insufficiency (POI) with the dominant-negative effect. BMP15-related ovarian dysgenesis (OD) constitutes 1.5-2.0% of POI. The underlying mechanism ...

Background: Hepatocyte nuclear factor 1β (HNF1β) is a critical transcription factor that regulates the development of the kidneys, pancreas, liver and genital tract. Patients with deletions and mutations in the HNF1 β gene present with renal and extrarenal manifestations. The most important extrarenal finding is diabetes, also known as MODY5. Although it is generally diagnosed with hyperglycemia, diabetic ketoacidosis is rarely seen.<p class...

Keywords: Syndromic Obesity, Child, GeneticsObjective: Syndromic obesity is accompanied by dysmorphic findings, motor and mental retardation, and organ anomalies. In this study, we aimed to evaluate the patients who were followed up with a diagnosis of syndromic obesity in our clinic.Materials and Methods: Demographic, clinical, and biochemical data of the patients followed up betwee...

Background: Next-generation sequencing (NGS) technologies have improved our knowledge about the genetic basis of congenital hypothyroidism (CH). The objective of our study was to evaluate the molecular genetic etiology in our primary CH cohort by using the NGS-based panel.Subjects and Methods: The clinical and genetic characteristics of 147 patients (61 female) from 129 unrelated families were evaluated. The patients wer...

Aim: The objective of our study was to investigate the physical examination and laboratory findings in obese children with or without primary headaches.Methods: A total of 161 children, aged 8-18, with obesity (90 female and 71 male) and primary headache, admitted to pediatric endocrinology and pediatric neurology department between 2013 and 2018 were evaluated retrospectively. Participants were divided into subgroups as with tension headache and migrain...
